I use Scrivener with iCloud, and it Just Works. Any sync issues - I've had a few, but they're not common - are down to iCloud. And Scrivener stores a very complete list of version backups, so you can always go back if something goes horribly wrong. Having said that - it is an infuriating piece of software. It feels like it was designed by someone who has some talent for solving small problems, but no clue at all how to combine them into a unified, elegant, intuitive app. The compile-to-output format feature should be studied in schools as a perfect example of how not to implement something. But... I still find it very useful for organising thoughts and for combining them while writing. On the hand a lot of it is a mess, on the other the core features have really helped to improve my workflow.
